MACHINE FOR CLEARING SILK OR OTHER TEXTILE THREADIS.`

A SPECIFICATION forming part of Letters Patent No. 653,174, dated July 3, 1900. Application filed May 12, 1898. Serial No. 680,480. (No model.)

To a/ZZ whom, it may concerne.-

Be it known that we, CHARLES GUILLAUME DIEDERICHS, manufacturer, and MARIE AU- GUSTE EUGENE MARQUELET, engineer, citizens of the Republic of France, residing at Ste. Colombe les Vienne, France, have invented a certain new and useful Machine for Clearing Silk or other Textile Threads, of which the following is a full, clear, and exact specification, reference being' had therein to the accompanyingdrawings.

This invention relates to a machine for effecting the easy and rapid clearing of threads submitted to its action and for freeing them from defective knots, Wisps, irregularities in thickness, doublings, doc., and which machine enables us to produce tissues or textiles of great uniformity and regularity, at the same time increasing production and avoiding faults or blemishes.

AThat our invention may be better understood we have shown on the annexed drawings an elevation, Figure l, of our machine, and a plan view, Fig. 2.

The thread A unwinds from a spool B, suitably supported, and iirst passes over a fixed glass rod C, then through the trimmer D, afterward over another fixed glass rod E, and

finally, after having passed over a glass rod F, acting as a guide, is Wound upon the spool G. The thread-guide rod F, mounted on a lever oscillating or pivotingr around an axis f, (see Fig. 1,) directs or guides the thread A in its Winding on the spool G. The spool G is mounted on a spool-carrier or winding-spindle g, supported in a bearing adjustable for height. On this spindle g is tixed a pulley g2, which engages an endless strap H, passing over drums, such as 7L, suitably arranged and operated. The pulley g2 can be thus driven, and the spindle g consequently receives a rotatory movement. The strap H can be tensioned by the help of a tension roller h, mounted on a support h2, furnished with a bearing or socket h3, of which the position is adjustable for height by means of aset-screw h4. The roller-support It is fixed to a portion of the machine I, which ordinarilyis an angleiron secured upon a support t', fixed on the connecting cross-piece J.

T he instantaneous stoppage of the spindle .upon or retardation of the spindle.

g can be effected or performed by means of a band-brake K, which may be caused to act on the pulley g2 adjacent thereto. The band of this brake is fixed to the end or bottom of the beam L.

The trimmer D is a sort of draw-plate and may be of metal, glass, or agate. Itismonnted on a carrier d by means of a plate-spring CZ, which secures it in place. This method of attachment facilitates the rapid replacing or substitution of trimmers, which are so made as to be interchangeable and are numbered so as to allow a rapid controlof the same, with a vieW to recognizing if the trimmer in position corresponds to the n umber of the thread. The carrierd can pivot on its axis d2, mounted on a support cl3, fixed to the cross-piece M, which latter is also furnished with the stepbearing g. The trimmer and its carrier are balanced bya sliding Weight d4. To the carrier d is secured a rod N, capable of raising the toggle-,levers or hinge O, which acts in its turn on a lever P to cause the throwing into gear of the machine, the disengagement or throwing out of gear, and the brake-action This hinge O is arranged in such a manner that When its two portions o o are parallel or not inclined at an angle to each other a part or lever Z bears upon the arm 7J of the lever P, pivoted at p and acting as a guide for the spindle g. This latter is then in such position that the roller g2 is in contact with the driving strap or band I-I. When the rod N is raised, it bears upon the hinge O, so that the two parts of' the latter form a more acute angle. The part O leaves the arm p of lever P, which is then acted on solely by a spring p2. The pulley g"2 first separates from the band H and then comes into contact With the part K, acting as a brake, which causes the immediate stoppage of the spindle g. Thev lever P is pivoted atp on a support Q, mounted upon the plate or beam L, and its position is adjustable by means of a screw q. lThe hinge o is xed to a support o2, secured to the beam L, and the position of which is adjustable by means of a screw o3.

To enable the spool Gto easily revolve, so as to Wind or unwind the thread, it is necessary to provide means for maintaining the ICO spindle gin an intermediate and free position, the pulley g2 bein gin contact with neither the strap H nor the brake K. For this purpose on the lever P is fixed by a pivot r a click or catch R, capable of engaging a notch l', formed inthe beam Land corresponding with the intermediate position of the lever P.

The operation of the machine above described is as follows: The thread A, unwinding from the spool B, reaches the trimmerD. If a kink, knot, or projection is presented thereto, it raises this latter, which is balanced byits counterweight d4. The carrier d is then raised and swings on its axis and raises the rod N. This latter abnts against the under side of the disengagement-hinge O, the two parts of which then form an angle and, ceasing to maintain the lever P, allow the spring e2 to pull it over. The pulley g2 leaving the strap, the spindle is disengaged and is stopped immediately, because the pulley g2 at once comes in contact with the band-brake K. Vhen a stoppage has been effected and the thread has been put in order, we proceed as follows for the subsequent operations: After having lowered the carrier d on the glass rod C the lever P is replaced in the position in which the pulley g2 is in contact with the strap H, which rotates the spindle g. This position is insured by the hinge O.

To be able to cause the spool G to turn freely, so as to wind or to deliver or unwind the thread A, we proceed as for the starting; but in place of pushing the lever P to the end of its stroke we stop it opposite the recess Z, Fig. 2, and cause the catch R to engage this notch. The spindle g2 can then rotate freely. In this position to cause starting we have only to push the lever P, the catch R being raised at the same time out of the recess W, Fig. 1.

The disengagement-hinge O possesses the great advantage of necessitating only a minimum force to cause disengagement. The result is that our machine suits all kinds of thread, even the very finest. Stoppage is immediate and does not involve a risk of breaking the thread.

To hold the trimmer D, its carrier (l is furnished with spring d', secured thereto by means of rivets. This spring allowsthe trimmer to be quickly changed or replaced, according to the thicknesses of thread to be wound. The trimmers are preferably numbered, so that we can easily notice if the numbers in place correspond with the numbers of the threads treated.

The number of spindles mounted on the machine is variable. In the portion of the machinev shown in plan on Fig. 2 there are three spindles. The first, l, is in gear, the second,

2, is out of gear, and the third, 3, is in gear.

The mechanism described has been shown in connection with the spindles Nos. 2 and 3.

It should be understood thatwe may modify the machine above described without departing from the spirit of our invention.

l/Vhat we claim as our invention, and desire to secure by Letters Patent, is-

1. The combination of the driving device, the winding-spool adapted to engage the same, the lever in which said spool is journaled off the center or f nlcrum of the lever7 the togglelevers connected at one end with a stationary support, and at the other with the first-named lever at a distance from its fnlcrum, a trimmer through which the thread is adapted to pass, said trimmer being movable by irregularities of the thread, and an operative connection whereby the movement of the trimmer will actuate the toggle-levers.

2. The combination of the driving device, the winding-spool movable into and out of engagement with said driving device, the hinged or toggle levers connected to the spindle of the spool to shift the same, a trimmer through which the thread is adapted to passy, said trimmer being movable by irregularities of the thread, a spring for drawing the toggle-levers together or keeping them in an extended position, and a tripping-rod actuated by the trimmer to throw the toggle-levers ont of the extended position.

3. The combination of the driving device, the winding-spool movable into and out of engagement with said driving device, the hinged or toggle levers connected to the spindle of the spool to shift the same, a trimmer through which the thread is adapted to pass, said trimmer being movable by irregularities of the thread, and an operative connection whereby the movement of the trimmer will actuate the toggle-levers.

4E. The combination of the winding-spool, driving mechanism on one sidethereof,abrake on the other side of the spool, the latter being movable between the driving mechanism and the brake, a trimmer through which the thread is adapted to pass, said trimmer being movable by irregularities of the thread, an operative connection whereby the movement of the trimmer will throw the winding-spool from an engagement with the driving mechanism to an engagement with the brake, and means for holding the spool in an intermediate position.

In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
